Window replacement costs $400 to $650 per window installed for vinyl and $700 to $1,000 per window for wood. Prices vary depending on the size, type, and brand. For new constructions, add $50 to $100 per window for installation. 

Vinyl and composite are often the least expensive and most common window options. Wood frames provide better insulation but cost more and are harder to maintain. Clad frames are the most expensive option but last longer because they're made with vinyl-encased wood.

Windows are installed by following these steps:

1. Removing the old window
2. Applying caulk
3. Inserting the new window
4. Securing the frame
5. Cleaning the trim and floor

Many installers replace windows from the outside to minimize mess, except in wintertime or inclement weather.

Installing windows takes 30 to 60 minutes per window, depending on the size, type, and accessibility. Large or ornate windows take longer to install than small, simple windows. Installers can work faster on first-story windows than they can on second-story ones.

Manufacturers recommend replacing windows every 20 years on average. Window warranties typically last 5 to 20 years, although some are covered for as long as you own your home. Consider replacing windows if they:

• Are hard to open
• Have warping or rotting frames
• Are foggy between double-paned windows
• Don't insulate well, which increases energy bills

Windows are installed by professional window fitting companies, glaziers, or handymen. Popular companies that offer window installation services include Renewal by Andersen, Champion, Home Depot, and Lowe's.

Tipping window installers and other contractors is not required or expected. However, you may tip $20 to $30 per person if you feel that they went above and beyond.
